Ok so technically it's a Bacon grease powered motorcycle, but that is still pretty badass!
Check out their full website about the process of converting Bacon grease into bio-diesel, the full details of the bike build, the journey as they ride the motorcycle across the US as well as many other interesting stories.
This really is one of the coolest things I think I've posted here. Love this idea.
And it's a pretty cool looking bike too!
Good skills and keep it going!
